Hello everyone and thanks in advance for your help. I am on my 2nd BB 8310 (AT&T) and I take great care of it. Today I pulled it out of the holster and the screen was suddenly yellowed and garbled. I did a soft reset and the screen was all white. Removed the battery and did a hard reset, and the screen is now black. It is capable of receiving calls but the hot keys don't seem to work. I luckily was able to hook it up to the computer and even in this state was able to sync and back up. I was weary, however, if nuking the BB starting factory fresh would work, but it's the only thing I haven't tried. Also tried wall recharger.
No drops, no water, no intense electrical or magnetic fields, and have had this new model since late November. I'm a crisis responder and I'm useless without the phone, and since it's stuck on vibrate, I don't know if I have incoming calls, emails, texts, etc.
